High CPU for multiple processes Microsoft 365

In the last several days I have noticed my laptop CPU fan blowing constantly. The culprit seems to be 4 identical processes using the same amount of CPU as each other continuously hovering at about 8-12%. This keeps the fan blowing 24/7.

The Task Manager shows the Process name as "Microsoft 365 and Office (32 bit)" and no Office applications are running. When I view the details the executable names are "odt____.tmp.exe" with the underscores representing some 3- 4-character hex value, e.g. C67A.

I can end the tasks but they come back after a time and the CPU fan turns on again.

What are these processes and can I turn them off?

TIA

BTW, I tried to include a screenshot, but the image upload doesn't work.

    I also did nothing and the last time it spun up and ate CPU was in the early AM PST of 1/10. In the afternoon and this morning nothing. Checked C:\Windows\Temp and found new cfg and odt files. Only updates in update history:

    Of course, this thing reaches out to Microsoft in the cloud, and something out there has likely changed.

    I did not some logs in the same folder. Did a couple of compares and then lost interest. But did note that older, failing versions had 8 instances of "Office.Experimentation" object where working one had only 1. But this may be total coincidence and hard to diagnose without correct tools to parse logs.

    But IMHO, Microsoft fixed. If I see back, I will post another reply.

    Safe Computing!

    Thank you for the suggestion, but I don't see that process or task.

    I had the same issue but when I killed them they didn't seem to come back.

    See if you have a process called CacheTask, it was the only task running and something is starting them. I couldn't test because they didn't come back.

    Get-ScheduledTask -TaskName CacheTask 

    To stop it

    Get-ScheduledTask -TaskName CacheTask | Stop-ScheduledTask
